"This occurred at a restaurant in Crystal City (Virginia), and everybody was aware of it," Wilson said on the station. "It was only a matter of time because so many people were aware of what took place, so many people were aware of her situation, the fact she left — everybody knew with the campaign that this would eventually come up."

In an interview with POLITICO, Wilson said he was present for the episode and that it took place in the late '90s.

Wilson declined to say specifically what Cain said or did to the woman, but that the CEO's actions made other individuals at the table uneasy.

"It was very uncomfortable," said the pollster, recalling that other individuals present asked Cain to stop.

Wilson said there were at least three other people at the gathering but wouldn't share the name of the woman for publication.

The Cain campaign didn't respond to an email asking if they had a comment on the incident.

Wilson is a Rick Perry supporter and does polling for a Super PAC that supports the Texas governor's presidential bid.

The pollster requested that POLITICO make clear that he has not shared this story with any of his clients and that he was not the source for the original story Sunday on the two women who complained about Cain at the association.
